Molecular biology glossaries and terms

Nucleotide-binding domain

Biology; Biochemistry

One of the homologous supersecondary structures of some proteins, composed of Rossmann folds, to which may be bound the AMP moiety of a substrate or ligand; e.g. the domain of a dehydrogenase that ...

Retention of configuration

Biology; Biochemistry

The lack of a change in the configuration at an asymmetrical centre over the course of a reaction, e.g. the enzymic addition of an α-glucosyl unit to glycogen from UDP-glucose, which is itself an ...

Post-transcriptional modification

Biology; Biochemistry

The processing of RNA subsequent to its synthesis. May include hydrolysis and transesterification of phosphodiester bonds and modification of bases. For eukaryotic mRNA it includes capping of the ...

Troponin

Biology; Biochemistry

A complex of three proteins (TnI, TnC and TnT) that interacts with tropomyosin to control cross bridge formation during skeletal and cardiac muscle contraction. Troponin concentrations are elevated ...
